Last night when I started my 2009 328xi I received a "Restraint System Malfunction!" message on my nav screen. It indicates that its a passenger restraint system issue (Fault in passenger-restraint system affecting airbag, belt tensioner or belt-force limiter. Continue to wear the safety belt. Have the system checked by the nearest BMW center). I did a little research and seems to be a recall for 2006 e90s but not other years. Has anyone else encountered this? Common issue? Is there any danger in driving? What could have caused this? Any insight would be appreciated.
